在20世纪90年代,研究人员证明了BRCA1和BRCA2为遗传性乳腺癌和卵巢癌的致病基因[1]。 时至今日,我们都知道携带BRCA1和BRCA2基因突变的人群患乳腺癌和卵巢癌的风险增加,且BRCA1和BRCA2突变携带者患乳腺癌的风险与被诊断为乳腺癌的近亲数量呈正相关[2]。 随着对这两个基因研究的深入,人们发现在前列腺癌和胰腺癌中...
BRCA1致病性突变与5种癌症的疾病风险增加显著相关,包括卵巢癌(OR=75.6)、女性乳腺癌(OR=16.1)、胆管癌(OR=17.4)、胃癌(OR=5.2)和胰腺癌(OR=12.6);BRCA2致病性突变与7种癌症的发病风险增加有关,包括女性乳腺癌(OR=10.9)、胃癌(OR=4.7)、卵巢癌(OR=11.3)、男性乳腺癌(OR=67.9)、胰腺癌(OR=10.7)、前列腺癌...
One hundred and eighty patients were subsequently offered testing with 161 accepting (161/180, 89%). Nine patients were found to harbour pathogenic variants in either BRCA1 or BRCA2 (9/161, 6%). Of the initial 2044 patients reviewed, 2.7% (56/2044) are now known to carry germline ...

对于符合NCCN指南检测标准的患者，应当积极完善BRCA1/2基因检测，不符合检测标准的患者，如果经济条件尚可，也建议进行BRCA1/2。参考文献：[1]. Beitsch PD, Whitworth PW, Hughes K, et al. Underdiagnosis of hereditary breast cancer: are genetic testing guidelines a tool or an obstacle? J Clin Oncol ...
一、Brca1基因和Brca2基因概述 Brca1基因和Brca2基因都是常染色体显性遗传的肿瘤抑制基因,参与DNA的损伤修复和转录调控。研究表明,Brca1/2基因突变的肿瘤细胞对PARP抑制剂的敏感性显著高于正常细胞,通过抑制PARP-1的活性可使Brca1/2基因突变的肿瘤细胞发生合成致死。修饰酶PARP-1(Ⅰ型多聚ADP-核糖聚合酶,poly(ADP...
Definition BRCA1andBRCA2are tumor suppressor genes that when mutated place a patient at higher risk of breast and ovarian cancer. Genetic testing can be performed to evaluate for the presence of aBRCA1orBRCA2mutation. Patients with a strong family history of breast and ovarian cancer may benefit...
